Increasing evidence indicates that these changes — summarized by the term ocean acidification (OA)-- can significantly affect marine food webs and biogeochemical cycles.

The consensus is that several factors are important: atmospheric composition (the concentrations of carbon dioxide, methane); changes in the Earth's orbit around the Sun known as Milankovitch cycles (and possibly the Sun's orbit around the galaxy); the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on the Earth's surface, which could affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth - Moon system; and the impact of relatively large meteorites, and volcanism including eruptions of supervolcanoes.

However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant photosynthesis and water use efficiency, and ocean acidification).
